With BlackBox, You'll Know Before They Mail.

The Predictive Abuse-Prevention Solution for Email Service Providers

BlackBox is the world's most comprehensive resource for finding potentially problematic email addresses, allowing ESPs to preemptively score the quality of their senders' lists and manage senders more effectively.

Predict Behavior

Predictive scoring ensures consistent, reliable decisioning. Using BlackBox as the backbone of a custom scoring model not only lets ESPs predict risk, but improves customer onboarding and ultimately enhances deliverability.

Educate & Reward

It's not just about the preemptive detection of spammers; it's also a way to inform unwitting senders about problems with their list and to reward good senders.

Expedite Vetting

User vetting used to be laborious and time-consuming. With BlackBox, good senders can quickly be put on the approval fast track.

Improve Deliverability

The more abuse you prevent, the more you protect your systems against IPs that are blacklisted by email gateways and ISPs.
